ACETYLENE-GAS G EN ERATO R.

SPECIFICATION forming part of Letters Iatent No. 655,4;46, dated August7, 1900.

Application filed October 5, 1899. Serial No. 732,611. (No model.)

To all whom it may concern:

Be it known that 1, JOHN LAWRENCE, acitisuch as will enable othersskilled in the art to which it appertains to make and use the same.

The invention relates to improvements in acetylene-gas generators; andthe object of the invention is to simplify and improve the constructionand increase the efficiency of the machine.

To this end the invention consists in certain features of constructionand combination of parts, which will be hereinafter fully described, andparticularly pointed out in the claim.

In the accompanying drawings, Figure 1 is a vertical section of myimproved acetylenegas generator. Fig. 2 is a similar view taken at rightangles to the section shown in Fig. 1. Fig. 3 is a detail perspectiveView of the carbid-basket removed from the bell. Fig. 4 is a detail viewof the mouth of the hell, with a portion of the wall broken away to showthe condenser-chamber. p

In the drawings the same reference characters indicate the same parts ofthe invention.

1 denotes the tank, and 2 the bell.

3 denotes a relief-pipe which forms a safetyvalve in the event of thegas generating faster than it is consumed. The relief-pipe 3 is formedintegral with the bell 2 and projects slightly through the top of thesame, as shown in Figs. 1 and 2;

4.- denotes the condenser-chamber fixed in the mouth of the bell; and itconsists of horizontal plates 5 and 6, which form the parallel top andbottom of the condenser, the bell forming the curved wall thereof andthe plate '7 forming the straight wall, the condenserchamber beingair-tight with the exception of the inlet-pipe 8, which extends abovethe carbid-basket 15, and the outlet-pipe 9, which extends up throughthe top of the bell and terminates in a stop-cock 10. In practice thecondenser-chamber may be made separate caped.

and complete and afterward removably attached to or soldered in thebell.

12 represents a socket fixed to the inside of the bell, and 13 denotes abracket removably secured in said socket. The upper end of the bracketterminates in a horizontal arm 14, to which the carbid-basket 15 isfixed.

The operation of the device is entirely automatic and simple. Thecarbid-basket is first charged and then inserted in the bell, which isconveniently done by tilting the bell, so that the basket will enter themouth of the bell between the straight wall of the condenser-chamber andthe curved wall of the bell and the bracket inserted in the socket inthe bell.

The bottom of the carbid-basket is horizontal, and it will be noted thatthe horizontal arm of the bracketextends across the cen-- ter of thebottom of the carbid-basket to act as a brace and prevent the basketsagging at the bottom.

In operation the tank 1 is partially filled with water about two-thirdsfull. The bell 2 is then placed within it, and the air-cock 10 isopened, permitting the air to escape from said hell 2 through the pipe9, the stop-cock 10 being again closed after the air has es- The bell 2will then sink by its own weight until it is stopped by the stop-cock 1Oengaging the top of the tank 1. A'sufficient quantity of calcium carbidis then placed in the carbid-basket 15, which as soon as the calciumcarbid comes in contact with the water generates the gas which fills thebell and is permitted to'escape at the stop-cock 10 for consumption,except when the gas is being generated faster than it can be consumed,

when the surplus gas escapes through the reis' claimed, and desired tobesecured by Let ters Patent of the United States, is-

In an acetylene-gas generator, the combination with the tank 1, of thehell 2 provided said bell 2 and terminating at its upper por tion in thehorizontal arm 14; and the carbid- I basket 15 fixed to said horizontalarm 14; substantially as set forth.

In testimony whereof I have hereunto set my hand in presence of twosubscribing Witnesses.
